1, the degree of warmth is different under the same conditions.

Under the same conditions, the warmth retention of goose down is slightly higher than that of duck down. This mainly depends on the amount of fixed air in down, that is, fluffy and thick things keep warm, and the size of down fiber is directly related to the amount of fixed air. The volume of goose down fiber is larger than that of duck down fiber, and the constant air volume is larger than that of duck down fiber, so goose down is warmer than duck down.

2. The filling weight is different under the same conditions.

White duck down: under the same conditions, the warmth retention of duck down is slightly lower than that of goose down, and the net weight of filled down is greater than that of goose down.

White goose down: under the same conditions, the warmth retention of goose down is slightly higher than that of duck down, and the net weight of filled down is smaller than that of duck down.

3. The cashmere content is different.

White duck down: generally, the highest down content is 85 ~ 90, that is, the down content in 100 weight unit is 85 ~ 90 units.

White goose down: the down content can reach 90 to 95, that is, the down content in 100 weight unit is 90 to 95 units.

4. The swelling degree of cashmere is different.

White duck down: The swelling degree of domestic duck down is about 450, that is, one ounce of duck down is about 450 cubic inches under the pressure of 68.4 grams.

White goose down: The swelling degree of domestic goose down ranges from 450 to 600, that is, one ounce of duck down has 450 to 600 cubic inches under the pressure of 68.4 grams.

5, the smell is different.

White duck down: Ducks are omnivores, and there is a fishy smell in the down. Although it can be eliminated after treatment, the smell can still be reflected after one or two years.

White goose down: Goose is a herbivore, and there is no peculiar smell in the down.
